custody supervision order (“IRCS”) — Youth court judge
allowing Crown’s application to have youths sentenced as
adults and youths sentenced to life imprisonment with no
parole for ten years — Youths’ sentence appeal allowed —
Youth court judge erring in concluding that IRCS order
would not meet youths’ rehabilitation needs — Youth court
judge erred in holding that youth system lacked sufficient
provisions for enforcement of IRCS orders, and that youth
sentence had to be reduced by credit for pre-sentence custody
— Presumption of diminished moral blameworthiness for
youths focuses on assessment of maturity, moral sophistication and capacity for independent judgment of an adult —
Crown not overcoming presumption of diminished moral
blameworthiness for either youth — Had Crown overcome
presumption would still have borne onus of showing that
youth sentence being inadequate to hold youths accountable
— Court concluding that when deciding whether youth sentence adequate, permissible to impose maximum youth sentence in addition to pre-sentence custody and time spent
serving adult custody — Adult sentences set aside and youth
sentence of ten-year IRCS order made to commence when
appellate judgment released.
